pg.solver.solveFiniteElements(mesh, a=1.0, b=0...) does not work if b is set as a field

[gockolori]

Problem description

pg.solver.solveFiniteElements(mesh, a=1.0, b=0...) does not work if b is set as a field (just like a)

because "if b!=0" does not work any more in python 3.7.3

Your environment

Operating system: e.g. Windows, Linux
Python version: 3.7.3
pyGIMLi version: Output of print(pg.__version__)
Way of installation: conda forge

Expected behavior

I should be able to set a parameter field

Actual behavior

File "", line 17, in
bc=bc, times=None, userData=None, verbose=True)# **kwargs
File "/home/veronika/miniconda3/lib/python3.7/site-packages/pygimli/solver/solver.py", line 1593, in solveFiniteElements
if b != 0:

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
